I want a multi-column dropdown. Infragistics has the UltraCombo. My problem, is while I can set the DisplayMember and the ValueMember in the listconverter, I do not know how to tell the control what columns (UltraGrid), to use in the dropdown.

I don't know if this is the only way, or the best way, but it works.  In this example, the Display Name is "FullName".  When the dropdown occurs, the dropdown grid shows "FirstName" in the first column and "LastName"in the second column.
 
Here is the code

All you need to do is add an Event Handler for the Enter event for the UltraCombo:

void managerUltraCombo_Enter(object sender, EventArgs e) {

this.managerUltraCombo.Layouts.Grid.Rows.Band.Columns["FirstName"].Hidden = false;

this.managerUltraCombo.Layouts.Grid.Rows.Band.Columns["LastName"].Hidden = false;

this.managerUltraCombo.Layouts.Grid.Rows.Band.Columns["FullName"].Hidden = true;

}
